Definitions

  • the high-side part comprising a level shifter, a driver, a latch part comprising a latch having a set input (slatch) and a reset input (rlatch) and configured to latch the driver to either an on-state or an off-state, and a further circuit, wherein the latch part is configured and adapted to prevent the further circuit from drawing current from the power supply unless at least one of the set input is high and the driver is in the on-state.
  • the latch part is configured and adapted to prevent the further circuit from drawing current from the power supply unless at least one of the set input is high and the driver is in the on-state.
  • FIG. 3 shows a block diagram of a conventional latch part with an undervoltage lock-out circuit
  • FIG. 4 shows the conventional latch part of FIG. 3 in more detail
  • An undervoltage lock-out circuit measures the supply voltage V_suphs, relative to the floating ground—that is to say, the voltage Vhb at the half-bridge node. This voltage difference is compared with a reference voltage, and provided the voltage difference is adequate, the controller is allowed to operate; however, in case the voltage is less than the predetermined reference voltage, the controller is “locked out”.
